Applying the Brandon Method to Estimate the Concentration of Inorganic Nitrogen in Precipitation

A. V. Varenik

The interrelation between the concentration of inorganic nitrogen in precipitation in Sevastopol and preceding meteorological conditions is analyzed. An attempt is made to derive the equation of multiple nonlinear regression. It is shown that the application of the Brandon method allows estimating nitrogen concentration in precipitation with the error of ~35%. The larger error for higher concentrations of inorganic nitrogen can be explained by the impact of an additional anthropogenic source of nitrogen. The effect of this source cannot be described using meteorological data.
